What can you see if you're blind?

Answer 1

Nothing! Joking aside, there are several categories of what is considered "blindness". Statutory blindness or legal blindness is (in the US) any vision that is 20/200 or less in the better eye with the best correction possible. This means that a legally blind person would have to stand 20 feet from an object to see it, whereas a normally sighted person could stand 200 feet away from the same object and still see it. Additionally, people with an average acuity who have a visual field of less than 20 degrees are also classified as legally blind. Only about 10 percent of those classified as legally blind have absolutely no vision. The rest have some vision, ranging from light perception alone to relatively good acuity in comparison. === === * The term NLP, or "no light perception", describes those without any light perception or form whatsoever. This is what most people think of when they hear the word "blind". * A person with "light perception" can tell whether a room contains light or is dark. * A person with "light projection" can tell the direction of a light source. * A person with "form" can tell the basic shape of an object. * A person with statutory blindness is anyone with a visual field of less than 20 degrees or a visual acuity of 20/200 or less. * The term "low vision" is used to describe visual acuity from 20/70 to 20/200. Magnifiers and certain types of glasses may aid people with low vision. So what do people with NLP see? Nothing. For me, describing "nothing" to a sighted person is just as difficult as describing the color orange to a blind person - and perhaps more so.
